The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Jaconé.
The coming weeks are a bit of a mixed bag. There’s a clear pulse of decent swell coming through at the start, but after that, we’re looking at a real flat spell. The first standout is Thursday, September 3rd. Get on it early. That morning we’ve got a solid 7 ft south swell at 11 seconds, which is a nice, powerful groundswell. The wind is blowing offshore from the ENE at 12 mph, keeping things clean as a whistle. The combined energy is pumping at 1065 (moderate wave energy), and it’s calling for excellent conditions for experienced surfers. This is the highlight of the whole outlook.
Friday the 4th morning turns glassy with a north wind of 3 mph, but the swell drops back to 4 ft SSE. It’ll be clean but much smaller. After that, the wave energy just fades away. From Saturday the 5th right through to Monday the 14th, we’ve got a long stretch of poor to marginal surf. The swell gets tiny, periods get short, and the wind is all over the shop. There’s a glimmer on Monday the 7th morning with a 4 ft swell, but the period is a terrible 6 seconds – that’s just wind slop.
The next real standout pops up on Monday the 14th. A 5 ft east swell, with a short period of 7 seconds, but those consistent offshore NE winds at 12 mph will make it a fun, clean wave. The combined energy is 570 (moderate wave energy). It’s a good shout for a session if you missed the early stuff.
Then the last one to circle is Thursday the 17th. The morning shows a 5 ft SSW groundswell with an 11-second period and clean cross-offshore east winds. The combined energy is 578 (moderate wave energy). It looks promising, but being this far out, it’s a bit less certain.
Jaconé is an exposed spot, so it catches a lot. Keep in mind that the water temp is sitting at 73°, which is about 1° above normal – nothing wild, just a touch warmer than average for this time of year.
Let’s be honest: after that Thursday morning session, it’s mostly about waiting and hoping the forecasts improve. A good run of a few days of decent surf turns into a dead zone for a week. But when it’s on, it’s on.
Stay salty,
Rusty

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
